YouPin898 API
Mobile-first Chinese marketplace, quoted in CNY and converted to USD. Get YouPin898's lowest ask and listing count for 13,081 CS2 items, refreshed every 10 minutes — in the same response as Steam and 7 other marketplaces. Grab a free key or read the docs.
Why read YouPin898 through this API
YouPin898 is the second Chinese venue worth watching after Buff163, and the two frequently disagree by a few percent — which is exactly the gap arbitrage tooling looks for.
Like the other Chinese markets, YouPin898 quotes in yuan; we convert with daily ECB reference rates so the number is directly comparable to Skinport or CSFloat in the same response.
The point of a single API is that you are not maintaining 8 integrations. YouPin898 arrives in the
same shape as every other market: minor units, a currency, a listing count and a capture timestamp. Switch
?currency=EUR and every market converts together.
What you get for each YouPin898 item
- Lowest ask — the cheapest live listing, in integer minor units (no floats, no rounding drift).
- Listing count — how many listings sit behind that price, so you can tell a real floor from one lucky listing.
- Capture timestamp — when we last read it, per market. Never a silently stale number.
- Cross-market best — the cheapest venue for that item across all 9 sources, computed for you.
- Your currency — 30+ currencies via daily ECB reference rates.
Example: YouPin898 in a cross-market response
One request returns every market's live price for an item. Prices below were true when this page was built:
curl "https://steamdataapi.com/api/v1/items/AK-47%20%7C%20Redline%20(Field-Tested)/markets" \
-H "Authorization: Bearer sdk_YOUR_KEY"{

"markets": [

]
}At build time YouPin898 was asking $29.26 for that item with 10,000 listings, against $28.71 at the cheapest venue (csfloat). That gap is exactly what the best and spread fields hand you without comparing anything yourself.
Tracking YouPin898 prices over time
A single ask tells you today; a series tells you whether today is unusual. Every market accrues a daily lowest-ask point, so you can pull YouPin898's own history and compare it against Steam's median-sale series — which reaches back to 2013-08-13 and totals 15,581,753 daily points across the catalog.
curl "https://steamdataapi.com/api/v1/items/AK-47%20%7C%20Redline%20(Field-Tested)/history?source=markets&days=90" \
-H "Authorization: Bearer sdk_YOUR_KEY"The two series answer different questions. Steam's median is what items actually sold for, which lags but cannot be moved by one optimistic listing. YouPin898's daily low is what you could have bought at. Traders generally want both: the sale price to value a position, the ask to act on one.
From a YouPin898 price to a portfolio total
The same prices drive inventory valuation. Give the inventory endpoint a public SteamID and every item comes back priced — at the Steam ask and at cross-market real value, with YouPin898 included in the comparison — plus float, paint seed and Doppler phase where they apply, and a portfolio total in your currency.
const res = await fetch(

{ headers: { Authorization: "Bearer sdk_YOUR_KEY" } },
);
const { totalValue, items } = await res.json();YouPin898 versus the other markets we read
Item coverage differs a lot by venue. These counts are live from our own catalog:
| Marketplace | Items priced | Games |
|---|---|---|
| YouPin898 (this page) | 13,081 | CS2 |
| Skinport | 29,507 | CS2 + Rust |
| CSFloat | 27,360 | CS2 |
| Buff163 | 13,417 | CS2 |
| DMarket | 24,551 | CS2 + Rust |
| Waxpeer | 27,135 | CS2 + Rust |
| WhiteMarket | 27,054 | CS2 |
| C5Game | 13,425 | CS2 |
Steam itself is the ninth source: 29,458 CS2 and 5,397 Rust items carry a Steam ask, with median-sale history back to 2013 — 15,581,753 daily points in total.
Frequently asked questions
Does the YouPin898 API cover Rust as well as CS2?
YouPin898 lists CS2 items only, so this endpoint returns CS2 prices. For Rust, prices come from Steam, Skinport, Waxpeer and DMarket — see the Rust API.
How fresh are YouPin898 prices?
YouPin898 is re-read every 10 minutes. Every price carries a capturedAt timestamp so you can see exactly how old it is rather than guessing.
Do I get YouPin898 prices for Doppler phases?
YouPin898 does not expose the Doppler phase per listing, so phase prices come from the markets that do — WhiteMarket, Buff163, Waxpeer, DMarket and Skinport. Ask for ?variants=1 and you get whichever markets quote each phase.
Can I get historical YouPin898 prices?
Yes. Every market accrues a daily lowest-ask series, so /history?source=markets returns YouPin898's day-by-day price next to the others. Steam's median-sale series reaches back to 2013-08-13 and is on the same endpoint with ?source=steam.
What happens when YouPin898 stops listing an item?
It drops out of that item's markets array once its last capture ages past seven days, rather than showing a price nobody is offering. The cross-market real value keeps its last known figure, so a delisting does not turn your valuations into nulls.
Is this an official API?
No. This is an independent API that reads public marketplace data and serves it in one normalised shape. We are not affiliated with YouPin898, Valve or Steam.
